Patented Dec. 17, 1935 UNITED STATES PATENT OFFICE tor, Mass-, assignors to The American Steel and Wire Company of New Jersey, a corporation v New Jersey Application August 14, 1934, Serial No. 739,828 2 Claims. (Cl. 256-131) This invention relates to guard rails of the type using flat steel strips positioned in a vertical plane, one of the objects being to provide a con venient and practical means for tensioning the strips at all times regardless of the expansion and contraction due to temperature changes. Another object is to mount them on the posts in offset relationship. Other objects may be inferred.

Referring to the accompanying drawing:

Figure l is an elevationof a guard rail embodying the features of the invention.

Figure 2 is a top plan.

Figure 3 is a cross-section from the line III-- III in Figure 2.

More specifically, this drawing shows a guard rail including the combination of a post I and flat strips of metal 2 and 3 extending longitudinally to either side of this post in horizontal alinement and having overlapped portions 2 and 3 thereat.

Bolts 4 provide a means for interfastening these portions at points equally spaced to either side of the post I while other bolts 5 provide a means for interfastening the post and the one of the overlapped portions of the steel strips that is closest thereto, which is the portion 3 in the drawing. The combination also includes at least one compression spring 6 which is arranged in line with the post I so as to separate the portions 2' and 3'. The drawing shows two of these springs. In either case there is provided a means for elastically separating the portions i and 3 adjacent the post I.

Since the overlapped portions 2 and 3 are continuously elastically separated, the strips 2 statutes, it is to be understood that the scope of 10 the invention is not to be limited exactlythereto, except as defined by the following claims.

We claim:

1. A guard rail including the combination of a support, alined strips extending longitudinally to either side of said support and having overlapping portions thereat, means for interfastening said portions at points spaced to either side of said support, means for interfastening said support and one of said portions and means for elastically separating said portions adjacent said support.

2. A guard rail including the combination of a post, fiat strips of metal extending longitudinal- 1y to either side of said post in horizontal alinement and having overlapped portions thereat, means for interfastening said portions at points equally spaced to either side of said post, means for interfastening said post and the one of said portions that is closest thereto compression spring arranged in line with said post and separating said portions.
